HYDROCARBON-BURNER.

Specification of Letters Patent.

Patented Oct. 3, 1905.

Application filed January 27, 1905. Serial No. 242,337.

To aZZ whom it may concern.-

Be it known that 1, Cinemas R. HERRING- TON, a citizen of the UnitedStates, residing in the city and county of San Francisco, State ofCalifornia, have invented certain new and useful Improvements inHydrocarbon-Burners; and I do hereby declare the following to be a full,clear, and exact description of the same.

My invention relates to that class of hydrocarbon-burners especiallyintended for use in connection with the heavier liquid hydrocar-.bonsas, for instance, crude oiland which are designed more particularlyfor cookingstoves and other like structures.

The object of my invention is the production of an effective, simple,and inexpensive burner of that type in which an initial ignition of alimited quantity of oil is intended to furnish heat to a chamber withinits sphere of influence to generate combustible vapor from a body of oilmaintained in said chamber, the burner being quickly applied to thefire-box of an ordinary cooking stove or range and readily removedtherefrom for the purpose of renewal or repairs.

The essential features of the invention reside in the generating-chamberfor the combustible vapor and the means for supplying air to the burnersextending from the said generating-chamber.

To comprehend the invention, reference should be had to the accompanyingsheet of drawings, wherein- Figure 1 is an end view of an ordinarycooking-stove, partly broken away and sectioned, the hydrocarbon burnerbeing illustrated within the fire-box of the stove, the supporting-platefor said burner being partly sectioned. Fig. 2isalongitudinalsectionalview of the burner removed from the stove. Fig.3 is a plan view of the burner, and Fig. 4 is an end view of one of theair-supply pipes or tubes.

The numeral 1 designates an ordinary cooking-stove or other likestructure, and 2 the fire-box thereof, within which fire-box is locatedthe supporting-plate 3. This plate is cast with an upwardly-projectingrectangular flange 4:, which forms an open chamber 5 for the receptionof the oil used for initial firing.

The supporting-plate 3, which serves as a carrier for the burner, issupported in the fire-box 2 in any suitable manner. In practice it willrest upon the ledges 6 in the firebox, taking the place of the usualgrate, which is removed. In the supporting-plate 3 is made a centralaperature 6, which is surrounded by an upwardly-extending circularflange 7. The oil supply or feed pipe 7 ente'rs through the ash-pitopening and turning upwardly extends through the downward extension 8 ofthe vaporizing-chamber 8, projecting well up into said chamber, Fig. 2of the drawings. This vaporizing pan or chamber 8 is secured to thesupporting or carrier plate 3, its depending extension 8 fitting withinthe circular flange 7 upwardly projecting from the said supporting orcarrier plate 3.

Upon the vaporizing pan or chamber 8 is a cover 9, which forms a gas orvapor receiving chamber 9, said cover being provided with a superheateror dome 10. This dome receives and holds the vapor delivered into thechamber 9, so that the same may be superheated by the flame of theburner, and acts to maintain a constant pressure onto the gas or vaporwithin the chamber 9. From the cover 9 laterally extends the burner-tips11, through which burners the vapor or gas escapes from within thechamber 9. These tips are in line with the air-supply pipes or tubes 1212, which pipes or tubes are of such size as to permit of suflicient airflowing therethrough to cause proper combustion. The lower ends arefitted within the openings 13 13, formed in the supporting or carrierplate 3, the air entering therein from the ash-pit 14. or from beneaththe said supporting or carrier plate 3.

The cover 9 is held against displacement by means of the depending lugs15, which embrace the outer wall of the chamber 8 when the said cover 9is fitted onto the pan or chamber 8'. Between the upper surface of thevaporizing pan or chamber. 8 and the lower edge of the cover 9 anexit-space 15 is formed. Through this space the oil overflowing thechamber 8 escapes and flows into the open receiving-chamber 5, which oildelivered therein serves for the initial firing. I have found that acomparatively close fit between the cover 9 and the upper surface of thevaporizing pan or chamber 8 is the better practice, as even by theordinary inaccuracies of the metal an exit-space is left which willpermit the escape or the overflow of the oil from within the pan orchamber 8.

The oil is supplied through the pipe 7 until it fills and overflows thevaporizing pan or chamber 8, the overflow falling and trickling downinto the receiving -chamber 5 l/Vhen a sufficient quantity is in thechamber 5, the supply of oil is temporarily cut off by the valve 16 andthe oil in the chamber 5 ignited. The flame from the burning oil heatsup the chamber 8 and causes the vaporization of the oil therein. Thevapor or gas thus generated in the vaporizing-chamber 8 flows upwardinto the chamber 9 and escapes therefrom through the burner-tips 11 andis ignited by the flame of the initial firing. The supply of oil is thenresumed by the opening of the valve 16 and the required quantity of oilmaintained in the vaporizing chamber or pan 8, which is thereaftervaporized by the high temperature caused by the burning flame. As thechamber 9 becomes filled with the generated gas or vapor the sameescapes or flows into the dome 10 and is superheated therein by theburner-flame, which completely envelops the dome 10.

The ignition of the vapor or gas escaping through the burner-tips 11causes an upward air-draft through the air pipes or tubes 12 12', whichsupplies the required oxygen for perfect combustion. Y

The entire burner is readily separated and taken apart, inasmuch as theparts are not required to be bolted one to the other, and the saidburner can be easily placed into and removed from the fire-box of thestove.

Having thus described the invention, what is claimed as new, and desiredto be secured by Letters Patent, is-

1. A hydrocarbon-burner comprising a carrier or supporting plate havinga central aperture therein surrounded by an upwardlyextending circularflange, an open receivingchamber in said plate for the reception of oilfor initial firing, a vaporizing chamber or pan provided with adepending extension which fits within the upwardly-extending circularflange of the carrier or supporting plate, an oil-feed pipe passingupwardly through the said depending extension and extending well intothe vaporizing pan or chamber, a cover fitting onto the said pan orchamber and forming a gas-receiving chamber, an escape-passage betweenthe cover and the vaporizing pan or chamber for the outlet of anoverflow of oil, air-supply tubes extending upwardly from openings inthe carrier or supporting plate, said tubes terminating at diametricallyopposite points outside of the gas-receiving chamber and supplying tothe burner the req uisite air for proper combustion, and outlets formedin the wall of the gas-receiving chamber for the escape of the generatedgas.

2. A hydrocarbon-burner comprising a carrier or supporting plate, avaporizing-chamber connected thereto, means for supplying oil to saidchamber, a gas-receiving chamber communicating therewith and secureddirectly to and immediately above the vaporizingchamber, an outletbetween the said I chambers for permitting the escape of an overflow ofoil from within the vaporizing-chamber,

said overflow serving for an initial firing, a

superheater directly connected to and communicating with the interior ofthe receivingchamber for the vapor or gas, burner-tips extending fromthe vapor-receiving chamber, and means for supplying air to the burnersfor creating proper combustion, said means consisting of air-tubesleading from the supporting-carrier and terminating at point directlyopposite the burner-tips.

3. A hydrocarbon-burner comprising a carrier or supporting plate, avaporizing-chamber connected thereto by means of a depending extensionfitting within a circular flange upwardly projecting therefrom, meansfor supplying oil through the depending extension to the interior of thesaid chamber, a gas-receiving chamber secured immediately above andcommunicating with the interior thereof, an outlet between the saidchambers for permitting the escape of an overflow of oil from within thevaporizing-chamber, said overflow serving for an initial firing, asuperheater connected to the upper surface of and communicating with theinterior of the receiving-chamber for the vapor or gas, burnertipsextending from the vapor-receiving chamber, air supply tubes extendingupwardly from openings in the carrier or supporting plate, said tubessupplying to the burner-tips the requisite air for proper combustion.

In testimony whereof I have hereunto affixed my signature in thepresence of witnesses.
